Schönfeld, Joachim & Lübbers, Julia, 2020, Checklist, assemblage composition, and biogeographic assessment of Recent benthic foraminifera (Protista, Rhizaria) from São Vincente, Cape Verdes, Zootaxa 4731 (2), pp. 151-192 : 158

Genus Rosalina d’Orbigny 1826

Rosalina vilardeboana d’Orbigny 1839a , p. 44, pl. 6, figs. 13–15 [Plate 3, Figs. 7–9, Plate 6, Figs. 1 –5]. Cimerman & Langer (1991), p. 67, pl. 72, figs. 1–2. Jones (1994), p. 93, pl. 86, figs. 9a–c. Debenay et al. (2001), pl. 5, figs. 6,11. Note: the flattened test, wide umbilicus, and the short, triangular to comma-shaped umbilical flabs extending from the last chambers discriminate this species from other Rosalina species. The earlier chambers on the spiral side may be brown to orange-coloured.
